> If an HTML response in returned from the service to the client, due to a basic authentication
or other error, the following error stack is returned (if chunked transfer encoding is set
to FALSE for the HTTPConduit/client*):

> This requires the user to go to Wireshark[1] to determine what the HTML error message
is.  I think it would be helpful for the user if this error was trapped, and the HTML error
message output to the client console as part of the exception, to save that step.
> Steps to duplicate:  Make an HTTPS client connection to a server with (a) wrong username
and/or password and (b) chunked transfer encoding set to false as shown here:
